Corrosion resistance and dynamic anti-icing of superhydrophobic surface on ASW

Abstract

The superhydrophobic surface (SHPS) with a contact angle (CA) of 151°and a sliding angle (SA) of 0.5°was successfully fabricated on aluminium stranded wires (ASW) via a simple chemical etching process, and subsequently covered with a fluoroalkylsilane film. The wettability and microstructure of consequent SHPS was characterised by CA/SA, scanning electron microscopy and 3D colour laser scanning microscope, respectively. A simple dynamic icing experimental system was performed. The corrosion resistance and dynamic anti-icing property were also investigated by acid/alkaline solution corrosion and dynamic icing test. The results showed that, due to the combined effect of micro-nano structure, air cushion and capillary. The SHPS possessed great corrosion-resistant and anti-icing properties; moreover, the anti-icing property increased by 68.2% and the starting icing time was delayed by six times, which should be critical to the potential application in industry.

Recent advances in bioinspired superhydrophobic ice-proof surfaces: challenges and prospects

“…162,163 A lower ice adhesion allows the ice to be released from the surface with time under the action of wind or gravity. 164 Thus far, researchers have generally used the method of adding a layer of fats to the condensed liquid droplet and the solid surface to reduce the adhesion. [165][166][167] According to the different lubricants, they can be roughly divided into water lubricants and oil lubricants.…”

Stable and Durable Conductive Superhydrophobic Coatings Prepared by Double-Layer Spray Coating Method

“…Inspired by natural organisms, superhydrophobic surfaces, defined as surfaces with contact angles greater than 150 degrees and rolling angles less than 10 degrees, have attracted extensive attention from many experts and scholars [6][7][8]. They have been applied in specific fields due to their special properties, which include self-cleaning [9][10][11][12], corrosion-resistant [13][14][15], drag-reducing [16,17], and anti-icing abilities [18][19][20]. Superhydrophobic surfaces have been proven to possess excellent corrosion resistance [21,22].…”
